How Specific are Specific Comprehension Difficulties? An Investigation of Poor Reading Comprehension in Nine-Year-Olds

This study explores the incidence of poor comprehenders, that is, children identified as having reading comprehension difficulties, despite age-appropriate word reading skills. It supports the findings that some children do show poor reading comprehension, despite age-appropriate word reading, as measured with a phonological coding test. However, the proportion of poor comprehenders was smaller than the frequently reported 10–15%, and smaller yet, when average sight word recognition, measured with an orthographic coding test, was also set as a criterion for word reading skill. Compared to average comprehenders, the poor comprehenders’ orthographic coding and daily reading of literary texts were significantly below those of average readers. This study indicates that a lack of reading experience, and likewise, a lack of fluent word reading, may be important factors in understanding 9-year-old poor comprehenders’ difficulties.

关于小学阅读教学新模式的探讨

构建小学阅读教学新模式须反映新一轮基础教育课程改革的要求和网络环境建设的需要。通过阅读教学改革的研究和试验,我们构建了“以充分阅读求主动发展”的小学阅读教学新模式,它由育人环境、教学主张、功能目标、教学结构和教学程序五个部分有机组成。     

大学英语阅读与语篇分析能力

语篇分析(discourse analysis)是指对比句子更长,以交际为目的的语言片段所作的语言及交际功能的分析,它包括微观分析与宏观分析。语篇分析是大学英语阅读教学中不可缺少的方法和手段。在阅读教学中辨别篇章组织模式、识别衔接手段、了解文中修辞手法、找段落主题句等是建构学生语篇分析能力的有效途径。     

Nurturing Emergent Readers Through Readers Theater

Readers theater is a familiar literacy strategy for children who can read independently; however, it can also be used with younger children who have not yet developed independent reading skills. The purpose of this article is to adapt the concept of readers theater for use with emergent readers. It focuses first on defining readers theater and its many benefits, particularly in the areas of literacy development. Finally, it includes suggestions for successfully implementing a readers theater program with young children.

语文阅读教学目标设计

在语文阅读教学实践中,阅读教学目标经常被忽视,表现为:阅读教学目标设计不清楚、不突出、不正确。这是造成阅读教学效率不高、学生阅读能力偏低的主要原因。要根据语文教学大纲和学生的实际确定阅读教学目标设计的要点,给语文阅读教学的目标设计以正确的导向。     

The Effect of Questioning Style During Storybook Reading on Novel Vocabulary Acquisition of Preschoolers

The effects of adult questioning on children’s novel word acquisition during storybook reading were investigated. Three-year-olds were assigned to one of three conditions: vocabulary eliciting questions, noneliciting questions, and no questions (control). General vocabulary comprehension and novel word knowledge were equivalent across the groups before the storybook reading intervention. Children were read 3 storybooks repeatedly across 4 reading sessions and were tested for production and comprehension of novel words in the final session. Children’s novel word comprehension increased more in both question conditions than in the control condition, suggesting that type of question is not as important to word learning as children’s active engagement in discussion about novel words in general. Novel word production was not strongly affected by any of the reading conditions. However, asking children noneliciting questions did appear to foster production of new words more than not asking questions at all.     

复合材料叠层圆柱壳的非线性动力稳定性分析

本文用汉密尔顿原理导出了复合材料叠层圆柱壳的非线性动力稳定性的控制微分方程。在基本方程中包括了非线性大挠度、圆柱壳的初始几何缺陷,以及动力载荷的惯性力等因素的影响。本文的目的是分析复合材料圆柱壳的参数共振和确定壳体结构动力屈曲时的稳定性区域和不稳定性区域,作为求解的例题,本文对三种复合材料圆柱壳进行了数例计算:即 T300—5208石墨-环氧壳体,ARALL 叠层铝合金壳体,和 E-玻璃-环氧壳体,结果表明它们具有相当不同的动力稳定性能.由本文所得出的计算结果和分析结论对于考虑和设计复合材料圆柱壳的动力稳定性具有重要的实用意义.     

Review: Perspectives on the metallic interconnects for solid oxide fuel cells

The various stages and progress in the development of interconnect materials for solid oxide fuel cells (SOFCs) over the last two decades are reviewed. The criteria for the application of materials as interconnects are highlighted. Interconnects based on lanthanum chromite ceramics demonstrate many inherent drawbacks and therefore are only useful for SOFCs operating around 1000℃. The advance in the research of anode-supported flat SOFCs facilitates the replacement of ceramic interconnects with metallic ones due to their significantly lowered working temperature. Besides, interconnects made of metals or alloys offer many advantages as compared to their ceramic counterpart. The oxidation response and thermal expansion behaviors of various prospective metallic interconnects are examined and evaluated. The minimization of contact resistance to achieve desired and reliable stack performance during their projected lifetime still remains a highly challenging issue with metallic interconnects.
